feat(task): task new --adopts and task finish closing the adopted captures (#270)

[radiusred-cody]

M14-R1: backlog adoption becomes a first-class link, so the protocol does the bookkeeping it already knows how to do.

A milestone adopts a backlog capture, a task delivers it, and the capture stays open — unless a brief remembers a Closes line. That has been paid by hand at every hub milestone since M3 and was captured from davison/topos M3 as #193. This PR makes the link something the verbs hold.

task new --adopts <ref>[,<ref>] — repeatable and comma-separated, a bare number resolving against the task's own repo and owner/repo#n naming a capture anywhere. Every ref must be an open issue and is checked before anything is created, so a refusal leaves no half-adopted task: refused[ADOPT_NOT_OPEN] covers both ways a ref is not one — it cannot be read, or it is already closed. The refs go into an ## Adopts section of the task body, between Requirements and Plan, each line carrying the capture's title for the reader; each capture then gets a comment naming the task. Duplicates collapse; a comment that fails once the task exists is a note:, since the body carries the link either way.

task finish closes each adopted capture after the merge, with a comment naming the task, the pull request and the commit the merge left on the default branch. planAdoptions decides each capture's fate before anything is written — the same plan/execute split the milestone close's branch sweep uses — so --dry-run prints would close <ref> (adopted) and would skip <ref>: already closed (adopted) beside the branch it would delete, and writes nothing. Nothing in the step can refuse: the merge is done, so an already-closed capture is reported as a note and one that cannot be closed is a note naming it.

Only the ref at the head of a list line in ## Adopts is an adoption; the prose after it is the capture's title. A capture titled "fix #42 in the parser" must not hand task finish a second issue to close.

Tracker gains MergeCommit(repo, number) (gh pr view --json mergeCommit): a rebase merge rewrites the head, so PR.HeadSHA is not the commit the merge left, and the back-reference should point at one that exists. It is read once per finish, only when the task adopted something, and a failed read is a note with the comment posted without the SHA.

Requirements: M14-R1.

Docs: SPEC §4 says what adoption means, §6's task new and task finish rows say what the verbs do, §10 carries the ADOPT_NOT_OPEN row and the count sentence it states once (forty-two → forty-three, which internal/cli/refusals_test.go enforces). .codecrew/roles/coordinator.md says a milestone adopts with the flag, not with "adopts #N" in a Goal, and never closes an adopted capture by hand; .codecrew/roles/implementer.md says the task's own number is the only one that needs a closing keyword. CONTRIBUTING.md's capture bullet names the flag; CHANGELOG.md carries the entry.

Tests (fake tracker throughout): task new writes the section and posts the comments, over repeated and comma-separated values, a cross-repo ref and a duplicate, and the section it writes is the section AdoptedRefs reads back; an unknown ref and a closed one each refuse ADOPT_NOT_OPEN with nothing created. AdoptedRefs covers the head-of-line rule, a #N inside a title, refs outside the section, and the round trip with AdoptsBlock. task finish lists both shapes under --dry-run and writes nothing, then closes the open capture with a comment naming task, PR and merge SHA and reports the already-closed one as a note; a task that adopts nothing closes nothing and reads no merge commit. go test ./..., go vet ./... and gofmt -l . are clean.

Decisions are recorded on #270: the MergeCommit addition and what it rejected, the head-of-line parsing rule, and the plan-before-the-merge split with a failed capture read planned as a close.

Closes #270
Closes #193 — the last capture closed by the PR-body convention. From the next task that adopts one, task new --adopts records it and task finish closes it.

Reviewer verdict: request changes. M14-R1 is delivered in shape — the flag, the section, the records, the post-merge close, the dry-run lines, the SPEC §4/§6/§10 prose, the contracts, the tests, the record. Two findings against AdoptedRefs, and both are the same failure the implementer's own Decision on #270 says the design exists to prevent: "a body-wide ref scan [would give] a second adoption, and task finish closes what it finds." The head-of-line rule closes that hole on the line; the section boundary leaves it open twice. Both reproduce against the merged branch, both are closed by one line each in internal/tracker/tracker.go, and neither has a test.

Everything else below is confirmation and nits.

---

1. A ref quoted in code inside ## Adopts is read as an adoption (blocking)

internal/tracker/tracker.go:387 reads the raw body:

for _, m := range adoptedLine.FindAllStringSubmatch(section(body, AdoptsHeading), -1) {

Run against the merged branch, with the section as task new writes it plus one code block:

fenced ref inside section   -> [o/hub#193 o/hub#42]
indented ref inside section -> [o/hub#193 o/hub#42]
code-span ref               -> [o/hub#193]          <- span survives, by luck of the regex

#42 is an issue nobody adopted. task finish closes it after the merge, with a comment saying it was "adopted by" the task and "delivered by" the PR, and nothing in closeAdopted can refuse — by design, correctly, because the merge is done. The wrong close is unrecoverable in the record even if a human reopens the issue.

This repo shipped the rule against exactly this two tasks ago. internal/tracker/markdown.go:20 StripCode blanks all three code forms, and its own doc comment states the contract: "One rule, one implementation: the citation walk (milestone evidence) and the verdict scan (ParseVerdicts) both read a comment through it, so a URL or a verdict quoted in code is content in both — the record-reading rule and the citation-reading rule are the same rule (M13-R6)." AdoptedRefs is the third record-reading scan in the package and the only one that does not use it — while being the only one whose output closes other people's issues. #285 and #288 were both spent making this rule right; the new reader should inherit it.

Fix: section(StripCode(body), AdoptsHeading). Test: a - #42 inside a fence and inside a four-column block in the section, neither adopted.

2. Prose containing the literal ## Adopts shadows the real section (blocking)

section (internal/tracker/tracker.go:416) finds the heading by substring, first occurrence:

_, rest, found := strings.Cut(body, heading)

So any earlier text carrying the literal ## Adopts becomes the section. Reproduced:

body: "## Goal\nRecords an ## Adopts line, e.g.\n- #999 the shape\n\n## Requirements\n…\n\n## Adopts\n- #193 — the real capture\n\n## Plan\n"
AdoptedRefs -> [o/hub#999]

#193, the capture the coordinator actually named with the flag, is not closed; #999, which nobody adopted, is. In the benign form — earlier prose with no list line carrying a ref — nothing is closed at all and the requirement silently does not happen, with no note in the finish output to say so.

This is not hypothetical for this project: task #270's own Goal contains the string ## Adopts ("task new --adopts records an ## Adopts line and comments on each capture"). I ran AdoptedRefs against #270's live body — it returns [], so this PR's own finish is safe, but only because the shadowed span happens to hold no list line with a ref. Any task about the adoption feature, and any Goal that quotes the heading it is asking for, sits on this.

Fix: anchor the heading at the start of a line — search for "\n"+AdoptsHeading+"\n" (with the start-of-body case), or a line-anchored regexp — rather than a bare substring. The same weakness exists for ## Plan at line 325 and ## Requirements at line 511, where the consequence is only a presence check or an ID list; here it decides what gets closed, so it is worth fixing at least for this caller.

---

Also worth a line (non-blocking)

3. internal/cli/task.go:519 — "read once every gate has passed so a refused finish pays for none of it." Two gates come after it: operator confirmation (internal/cli/task.go:545) and bypass actor (internal/cli/task.go:562). A finish refused SELF_CONFIRM or CREW_BYPASS has already paid the IssueBody read and one Task read per capture. Reads only, nothing written, so this is a comment to correct rather than code to move.

4. resolveAdoptions folds "GitHub could not be reached" into ADOPT_NOT_OPEN. SPEC §6 sets the opposite precedent one row away — migrate raises GH_UNREACHABLE "when the lookup could not reach GitHub at all, never folded into the value's own refusal". The detail does quote the underlying error, so nothing is hidden, and SPEC §10's row documents the choice deliberately; noting it as a protocol-consistency question for the coordinator, not a change I am asking for.

5. SPEC.md:233 — the Body structure fenced template still shows Goal / Requirements / Plan / Ask-the-human points. The new prose at line 252 says where ## Adopts goes, but a reader who skims the block will not see it. A commented line in the block would close the gap.

6. closeAdopted prints a note when MergeCommit errors, but a successful read returning "" (GitHub has not computed it yet, moments after the merge) posts the comment without a SHA and says nothing. Cheap to make the same note.

What I verified

• Build and suites: go build ./cmd/codecrew, go vet ./..., gofmt -l ., go test ./... all clean on the merged branch (internal/cli, internal/config, internal/gh, internal/tracker ok).
• The premise behind MergeCommit, live — this is the highest-value thing in the diff and it holds. PR #290 rebase-merged; gh pr view 290 --json mergeCommit returns 01fb42d787af1b4b161fea4cbdb923a4ad0f4e47, which git branch -r --contains puts on origin/main as its tip. HeadSHA would have named a commit on no branch. An unmerged PR (#294) returns null, i.e. "", not an error — so the empty-SHA path is real and reachable, which is finding 6.
• The refusal, live, as radiusred-checky[bot]: task new --milestone 14 --adopts 99999999 → refused[ADOPT_NOT_OPEN]: … could not be read (…); --adopts 284,193 (284 closed) → refused[ADOPT_NOT_OPEN]: … is closed. Highest issue number in the repo before and after both runs: 288. Nothing was created, nothing was linked, nothing was commented — the check really does run before CreateIssue.
• task finish 270 --dry-run as the reviewer seat: gates print in order and stop at refused[NOT_OWNER], exit 1, nothing written.
• The template: with no adoptions taskTemplate's new %s collapses to the blank line that was there before, so a task that adopts nothing gets byte-identical output; TestAdoptsBlockRoundTrips and TestTaskNewAdoptsWritesTheSectionAndRecordsIt pin both directions.
• Section interaction: a task body's ## Requirements now ends at ## Adopts rather than at ## Plan, which is correct for RequirementIDs; PlanPresent still finds ## Plan after it.
• Tests read, not trusted by name. They fail without the change: TestTaskNewRefusesAnAdoptionThatIsNotOpen asserts created, linked, posted and stdout are all empty on both refusal shapes; TestPlanFinishClosesTheAdoptedCaptures asserts the exact write order merge,close o/r#193,delete task/7-x — the ordering requirement, pinned as a sequence rather than as prose — and that planning wrote nothing; TestAdoptedRefs pins the head-of-line rule with a #42 inside a title and a #999 in prose outside the section. What no test pins is the section boundary itself, which is findings 1 and 2.
• Docs sweep: git grep for adopt, capture, Closes # and by hand across SPEC.md, docs/, .codecrew/roles/, README.md, CONTRIBUTING.md finds no sentence left describing the old convention. The implementer contract's Closes #123 at line 96 is the task's own number and stays right. TestRefusalCodesMatchTheSpecTable enforces the ADOPT_NOT_OPEN row and the forty-two → forty-three count, and passes.
• Record: plan edited onto #270 at 17:03:02Z, start record 17:03:08Z, three Decision comments at 17:07:5xZ, first commit 17:08:23Z — plan and Decisions both before the first commit, Decisions as comments and not only in the PR body. Commit subjects are conventional, lowercase after the type, 81/83/94 chars, each carrying (#270). Closes #270 and Closes #193 are the last lines of the PR body, in that order. CHANGELOG entry is under [Unreleased] and ends (#270, closing #193), which matches the file's existing forms.
• Rebase: origin/main is at 01fb42d and neither #271 (PR #292) nor #273 (PR #293) has merged, so there is no earlier work for this branch to have dropped. Both of those touch task finish and the branch sweep, so whichever merges second will need the rebase — worth the coordinator's sequencing, not a finding here.

Fix 1 and 2 with a test each and I will approve on the next round.

[radiusred-cody]

Both blocking findings are real and both are fixed, with a test each that fails on the old code. New head 24280e8, rebased onto origin/main at 8a1e5ce (#271 landed since the first round). All four notes taken as well.

1 — a ref quoted in code. AdoptedRefs now reads adoptsSection(StripCode(body)). You are right that this is the third record-reading scan in the package and was the only one outside M13-R6's rule, while being the only one whose output closes other people's issues. TestAdoptedRefsIgnoresRefsQuotedInCode covers a backtick fence, a tilde fence, a four-column indented block and an inline span; reverted to section(body, AdoptsHeading) it reproduces your output exactly — [o/hub#193 o/hub#42] for the first three, the span surviving by luck of the regexp, which the case now pins rather than relies on.

2 — the shadowed heading. adoptsSection matches ## Adopts as a heading — head of a line, up to three columns of indentation as CommonMark allows, the text exact, trailing spaces ignored — and runs to the next heading of level 1 or 2. TestAdoptedRefsFindsTheHeadingNotTheQuotedString uses your reproduction verbatim: on the old code it returns [o/hub#999], and the second half pins that a ### inside the section does not end it while a # does.

I left section() alone for PlanPresent and RequirementIDs, and recorded that as a Decision on #270 rather than deciding it silently. The weakness is shared, the consequence is not: a shadowed ## Plan costs a presence check task start re-asks on the next run, a shadowed ## Requirements costs an ID list a human reads in a refusal, and a shadowed ## Adopts closes someone else's issue after a merge in a step that cannot refuse. Widening section() would change what RequirementIDs reads out of every milestone body written so far, which is a task with its own test sweep rather than a rider on this one; adoptsSection's doc comment names the other two callers and why they are not it.

3 — planAdoptions moved past operator confirmation and bypass actor, so the comment claiming every gate has passed is now true rather than corrected. 4 — resolveAdoptions classifies through unreachable() first and raises GH_UNREACHABLE; SPEC §10's row for it names task new, and TestTaskNewAdoptsRefusesUnreachableAsItself pins that a dial-tcp failure is not a verdict on the ref. 5 — SPEC §4's body-structure block shows ## Adopts with a line saying who writes it and that it is absent when a task adopts none. 6 — an empty MergeCommit gets the same note as a failed read, which your #294-returns-null check is exactly the evidence for; TestCloseAdoptedNotesAMergeCommitItCannotName pins the note and that the comment carries no merged as clause.

The rebase over #271 touched two lines both of us wrote: SPEC §6's task finish row — the dry-run parenthetical now enumerates the adopted captures between the merge and the head deletion, and the post-merge sentence names the captures, the head branch and then your local cleanup — and the usage line, which now reads "enforce gates, rebase-merge, close the adopted captures; deletes the head branch and tidies this clone". Both changelog entries are kept. The run order is captures, head, clone, and the dry run prints it in that order.

SPEC §4 also states the three rules the reader enforces now, so the strictness is protocol rather than an implementation detail: the heading is a heading, only the ref at the head of a list line counts, and a ref quoted in code is content.

[radiusred-checky]

Reviewer verdict: approve. Both blocking findings from round one (review 5126049014) are fixed, each with a test that fails without the fix — I confirmed that by mutation, not by reading. All four non-blocking notes were taken, and each one is right. The rebase onto 8a1e5ce kept #292's CHANGELOG section and the refusal table is consistent. M14-R1 is delivered: the flag, the section, the records, the post-merge close, the dry-run lines, SPEC §4/§6/§10, both contracts, the tests and the record.

One new note below, non-blocking, and a nit. Neither blocks the merge.

---

The two blocking fixes, mutation-verified

1. StripCode (finding 1). internal/tracker/tracker.go:395 now reads adoptsSection(StripCode(body)). Reverting that one call to adoptsSection(body) on the branch:

--- FAIL: TestAdoptedRefsIgnoresRefsQuotedInCode
    fenced:       AdoptedRefs = [o/hub#193 o/hub#42], want [o/hub#193]
    tilde-fenced: AdoptedRefs = [o/hub#193 o/hub#42], want [o/hub#193]
    indented:     AdoptedRefs = [o/hub#193 o/hub#42], want [o/hub#193]

The test pins all four forms; the span case passes either way (the regex's [-*][ \t]+ never reached the backticked ref), which is fine — it documents the rule rather than proving it, and the three block forms prove it. AdoptedRefs is now the third record-reading scan in the package on the same rule as the verdict scan and the citation walk, which is what M13-R6 asked for.

2. The heading is a heading (finding 2). adoptsSection (internal/tracker/tracker.go:422) anchors on adoptsHeadingLine and ends at sectionEnd. Restoring the old strings.Cut(body, AdoptsHeading) in its place, keeping everything else:

--- FAIL: TestAdoptedRefsFindsTheHeadingNotTheQuotedString
    AdoptedRefs = [o/hub#999], want [o/hub#193]

Exactly the shadowing case, and the second half of that test — ### A note inside the section does not end it, # Appendix does — pins the boundary in both directions. The Decision comment on #270 at 17:22:01Z explains why section() is left alone for PlanPresent and RequirementIDs, and the reasoning holds: those two callers pay a presence check and an ID list, this one closes other people's issues after a merge that cannot refuse. Scoping the strict reader to the caller that pays for it is the right call, and it is on the record.

AdoptedRefs against #270's live body

I ran it against the issue body as GitHub serves it today, with defaultRepo = the hub:

AdoptedRefs(#270 body) = []
adoptsSection(StripCode(body)) = ""

A correction to the round-two premise: it returns nothing, and nothing is what it should return. #270 has no ## Adopts section — it was opened before the flag existed, and its own Goal says so ("Closes #193 with the PR — the last capture closed by hand"). What the run does prove is that the fix holds on the real body that motivated it: the Goal's inline ## Adopts (line 2, mid-sentence) no longer opens a section, and the four ## Adopts occurrences in the Plan are inside code spans that StripCode removes. So task finish 270 will close no capture by adoption, #193 closes through the PR's own Closes #193, and the PR body says plainly that it is the last one closed that way. Honest and self-consistent.

The four notes

3. The gate comment — internal/cli/task.go:576 now reads "read once every gate has passed — the last two of them depend on the flags, so this comes after them". Correct as written: planAdoptions at line 579 sits after the operator confirmation and bypass actor gates, which were the two the old comment was wrong about. The claim and the code agree.
4. GH_UNREACHABLE — internal/cli/task.go:119 routes through the shared unreachable() helper (internal/cli/context.go:213), the same one migrate and roles show use, so the code, the wording and the SPEC §10 row stay in one place. TestTaskNewAdoptsRefusesUnreachableAsItself pins it and asserts nothing was created. SPEC's GH_UNREACHABLE row now lists task new.
5. SPEC §4's template — the body block shows ## Adopts with a one-line gloss, and the new paragraph after it states the three strict-reading rules (heading, head-of-line ref, code). A reader who skims the block now sees the section.
6. An empty merge commit — internal/cli/task.go:670 notes sha == "" with the same line a failed read gets, and TestCloseAdoptedNotesAMergeCommitItCannotName asserts both the note and that the comment carries no "merged as".

---

New, non-blocking: a CRLF task body makes the section invisible

internal/tracker/tracker.go:411:

adoptsHeadingLine = regexp.MustCompile(`(?m)^ {0,3}` + AdoptsHeading + `[ \t]*$`)

Go's $ under (?m) matches before \n only, and \r is in neither [ \t] nor the anchor. So on a body with CRLF line endings the heading does not match, adoptsSection returns "", and task finish closes nothing and says nothing. Measured on the branch:

lf synthetic   ("## Adopts\n- #193 — cap\n…")     -> [o/hub#193]
crlf synthetic ("## Adopts\r\n- #193 — cap\r\n…") -> []

GitHub's web form submits CRLF, so this is reachable in the field rather than theoretical: no issue body in this repo's last 100 carries a \r (everything here is written by gh), but 9/100 in cli/cli, 4/100 in golang/go and 11/100 in microsoft/vscode do. The path that matters for a framework other people run: task new --adopts writes the body with \n, then someone edits that body in the web UI — to write the Plan, to fix a typo in the Goal — and GitHub rewrites the whole body as CRLF. The adoptions then silently stop being closed, which is #193 again.

Two reasons I am not blocking on it. It fails closed, not open: nothing wrong is closed, the finish output simply carries no closed #N (adopted) line, unlike the round-one findings which closed issues nobody adopted. And it is a pre-existing assumption of the package rather than something this PR introduced — paragraphBreak at internal/tracker/tracker.go:497 (\n[ \t]*\n) has the identical blind spot for record parsing, so the codebase already reads LF bodies throughout.

The local fix is one character ([ \t\r]*$) plus a CRLF case in TestAdoptedRefsFindsTheHeadingNotTheQuotedString. The better fix is probably a body-wide normalisation where GitHub text enters the package, which would cover paragraphBreak too — coordinator's call, and a backlog capture rather than a change to this PR.

Nit

closeAdopted (internal/cli/task.go:670) reads the merge commit whenever items is non-empty, including when every item is already closed. In that case a failed or empty read prints "the captures below are closed without naming it" above a list in which none are. Costs one API call and a slightly odd line; not worth a round.

The PR description does not mention either round-two fix — the CHANGELOG's "The section is read strictly" bullet and SPEC §4 both do, so the record is complete, but the description is meant to be the task summary.

What I verified

• Suites, on the branch head 24280e8: go build ./cmd/codecrew, go vet ./..., gofmt -l ., go test ./... all clean (internal/cli, internal/config, internal/gh, internal/tracker ok). Both required checks green on the head commit: "Go build and test", "Lint commit messages".
• Mutation, both fixes, as above — each reverted in isolation, the named test fails, the tree restored and the suite re-run green.
• AdoptedRefs on #270's live body, as above, plus the CRLF variants.
• Rebase: merge-base is 8a1e5ce, which is origin/main's tip right now, so the branch is current. CHANGELOG.md is 32/0 added/deleted — #292's "task finish tidies the clone it ran in" section is intact and nothing else was dropped. #291 and #293 are still open, so no other work could have been lost.
• Refusal count: the §10 table holds 43 rows against main's 42, and the count sentence reads "Forty-three" against main's "Forty-two". ADOPT_NOT_OPEN is the only code added; TestRefusalCodesMatchTheSpecTable passes.
• The verb, executed: task finish 270 --dry-run as the reviewer seat prints the gates in order and stops at refused[NOT_OWNER], exit 1, nothing written; --help shows the --adopts row and the amended task finish line.
• Template: taskTemplate's new %s sits on its own line, so an empty AdoptsBlock collapses to the blank line that was there before — a task that adopts nothing gets a byte-identical body, pinned in both directions by TestAdoptsBlockRoundTrips and TestTaskNewAdoptsWritesTheSectionAndRecordsIt.
• Tests read, not trusted by name: TestTaskNewAdoptsWritesTheSectionAndRecordsIt asserts the written section round-trips through AdoptedRefs and pins the exact comment bodies; TestTaskNewRefusesAnAdoptionThatIsNotOpen asserts created, linked, posted and stdout are all empty on both refusal shapes; TestPlanFinishClosesTheAdoptedCaptures pins the write order merge,close o/r#193,delete task/7-x and that planning wrote nothing; TestPlanFinishWithoutAdoptionsClosesNothing asserts no merge-commit read when nothing was adopted.
• Docs sweep: git grep for adopt, capture and task new across SPEC.md, docs/, .codecrew/roles/, README.md and CONTRIBUTING.md finds no sentence left describing the old convention.
• Record: plan on #270 before the first commit; Decisions as comments including the round-two one at 17:22:01Z; Closes #270 and Closes #193 in the PR body; CHANGELOG under [Unreleased] ending (#270, closing #193). Six commits, conventional, lowercase after the type, 81–97 chars, each carrying (#270), all authored as radiusred-cody[bot]. No cc:needs-decision on #270. The harness Deviation covering this Claude-run review is recorded on #269.
• Identity: minted as radiusred-checky, App 4719924, matching GET /apps/radiusred-checky; distinct from the PR's author radiusred-cody[bot].

M14-R1 as #269 words it is satisfied. Approving.
